which is the best protocol for text chat, voice chat and sharing file

Question

In my current semester, I am studying the course of communications and networks. My teacher gave us an assignment to choose the best protocol for three different scenarios. I am new to this course, and I am not 100% sure. Please help me to solve this. Here is the question.

Assume you have two users A and B, who want to communicate with each other over a communication network. The applications they are using for this purpose can either make use of TCP or UDP protocol. Explain which of these protocols (TCP and UDP) will be the best to use in the following circumstances and why?

a) Both A and B want to send chat messages to each other.

b) Both A and B wants to do a voice conversation.

c) A wants to send a file of size 5MB to B.
